Antidepressants are a class of medication used to treat major depressive disorder, anxiety disorders, chronic pain conditions and to help manage addictions. Common side-effects of antidepressants include dry mouth, weight gain, dizziness, headaches, sexual dysfunction, and emotional blunting
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia. Most cells, both animal and plant, range in size between 1 and 100 micrometers and are thus visible only with the aid of a microscope.
All living organisms are made of cells and cellular products. The cell is the smallest structural, functional, and biological unit of all living organisms. It can capable of biosynthesis, replication and energy transformation. All cellular organelles carry out specific functions that are necessary for the normal functioning of the cell. Animal cells work together and function interdependently. Human cells vary in size, shape, and function. Most animal cells are so small they can only be seen with the aid of a microscope. Based on function, there are more than 200 different kinds of animal cells that help each system contribute to the homeostasis of the entire body. Despite their many differences, human cells have several similar structural features: a cell membrane, a nucleus, and cytoplasm and cell organelles.
The term “opiate” refers only to substances with morphine-like activity that are structurally related to morphine. Opioids are sometimes referred to as “narcotic analgesics” and opioid receptor antagonists as “narcotic antagonists”
Sympatholytic drugs (Adrenergic blockers) bind to the adrenergic receptors and prevent the action of adrenergic drugs.
These are drugs which block the actions of sympathetic division or catecholamines (adrenaline and noradrenaline).
They are competitive antagonists at both α and β adrenergic receptors.
Your sympathetic nervous system is best known for its role in responding to dangerous or stressful situations.
In these situations, your sympathetic nervous system activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger.
Its nerve fibers arise from the thoracic and lumbar regions of the spinal cord.
The autonomic ganglia are the synapses between preganglionic and postganglionic neurons. The postganglionic axons then go to the visceral effectors.
Acetylcholine is a neurotransmitter releases in the preganglionic nerve endings and Noradrenaline at postganglionic nerve endings.
The drugs which mimic the action sympathetic division are called sympathomimetics.
They show similar actions as that of catecholamines.
Sympathomimetic
They act by either by directly interacting with adrenergic receptors (alpha or beta) or stimulation of the adrenergic nerve endings.
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. ... The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus.
Hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. This involves coagulation, blood changing from a liquid to a gel.
Aminocaproates.
Antifibrinolytic Agents.
Estrogens, Conjugated (USP)
Hemostatics.
Tranexamic Acid.
Aprotinin.
Deamino Arginine Vasopressin
Sulfonamides (sulphonamides) are a group of man-made (synthetic) medicines that contain the sulfonamide chemical group. They may also be called sulfa drugs. Many people use the term sulfonamide imprecisely to refer only to antibiotics that have a sulfonamide functional group in their chemical structure.
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.
Anticoagulants are used to treat and prevent blood clots that may occur in your blood vessels. Blood clots can block blood vessels (an artery or a vein). A blocked artery stops blood and oxygen from getting to a part of your body (for example, to a part of the heart, brain or lungs).
A tissue is a group of similar cells that are specialized for a particular function.
The four basic fundamental types of body tissues are
1. Epithelial tissue
2. Connective tissue
3. Muscular tissue
4. Nervous tissue
Each type of tissue is characterized by specific functions. These tissues contribute to the overall health and maintenance of the body. These tissues combine to form organs. The various organs make up the systems of the body that allow us to function and survive in our complex world. Histology is the science that deals with the study of tissues.
In biology, the tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
The English word "tissue" derives from the French word "tissue", meaning that something that is "woven", from the verb tisse, "to weave".
Career scope and opportunities
Pharmacy is the health profession that links the health sciences with the chemical sciences, and it is charged with ensuring the safe and effective use of medication. The scope of pharmacy practice includes compounding and dispensing medications, and it also related to more modern services like patient care, including clinical services, reviewing medications for safety and efficacy, and providing drug information.
The demand for pharma graduates is high in sectors like - healthcare, research, manufacturing, medical marketing, pharmacovigilance etc. As a pharma graduate, you can take up job roles like - drugs inspector, drugs controller, hospital pharmacist etc.
Ever hear the term "bronchial asthma" and wonder what it means? When people talk about bronchial asthma, they are really talking about asthma, a chronic inflammatory disease of the airways that causes periodic "attacks" of coughing, wheezing, shortness of breath, and chest tightness.
According to the CDC, more than 25 million Americans, including 6.8 million children under age 18, suffer with asthma today.
Allergies are strongly linked to asthma and to other respiratory diseases such as chronic sinusitis, middle ear infections, and nasal polyps. Most interestingly, a recent analysis of people with asthma showed that those who had both allergies and asthma were much more likely to have nighttime awakening due to asthma, miss work because of asthma, and require more powerful medications to control their symptoms.
Asthma is associated with mast cells, eosinophils, and T lymphocytes. Mast cells are the allergy-causing cells that release chemicals like histamine. Histamine is the substance that causes nasal stuffiness and dripping in a cold or hay fever, constriction of airways in asthma, and itchy areas in a skin allergy. Eosinophils are a type of white blood cell associated with allergic disease. T lymphocytes are also white blood cells associated with allergy and inflammation.
These cells, along with other inflammatory cells, are involved in the development of airway inflammation in asthma that contributes to the airway hyperresponsiveness, airflow limitation, respiratory symptoms, and chronic disease. In certain individuals, the inflammation results in the feelings of chest tightness and breathlessness that's felt often at night (nocturnal asthma) or in the early morning hours. Others only feel symptoms when they exercise (called exercise-induced asthma). Because of the inflammation, the airway hyperresponsiveness occurs as a result of specific triggers.
These are substances produced by a wide variety of cells in the body, having strong biological activity. Autacoids generally act locally at the site of synthesis and release. So they have also been called ‘local hormones’. They have short duration of action. They usually exert their action at the site of inflammation, lesion and injury.
The autacoids also differ from circulating hormones in that they are produced by many tissues rather than in specific endocrine glands.
The classical autacoids are— Ex.
Histamine, Serotonin
Prostaglandins, Leukotriene, Heparin, Endothelins
Bradykinin, Angiotensin, Eicosanoids
Interleukins, TNFα (tissue necrosis factor),
Platelet activating factor
The cell is the smallest structural, functional, and biological unit of all living organisms. It can capable of biosynthesis, replication and energy transformation.
Parasympatholytics are the drugs that block or inhibit the actions of acetylcholine at postganglionic nerve endings and cholinergic receptors. They are also referred to as anticholinergics or cholinergic blocking agents or antispasmodics.
Anticholinergic drugs include atropine and related drugs- atropine is the prototype. Atropine is obtained from the plant Atropa belladonna. Atropine and scopolamine (hyoscine) are the belladonna alkaloids. They compete with acetylcholine for muscarinic receptors and block this receptors-they are muscarinic antagonists.
The parasympathetic division typically acts in opposition to the sympathetic autonomic nervous system through negative feedback control.
This action is a complementary response, causing a balance of sympathetic and parasympathetic responses.
Overall, the parasympathetic outflow results in the conservation and restoration of energy, reduction in heart rate and blood pressure, facilitation of digestion and absorption of nutrients, and excretion of waste products.
These are drugs that produce actions similar to that of Acetylcholine hence known as parasympathomimetics.
They act either by directly interacting with cholinergic receptors or by increasing the availability of Acetylcholine at these sites.
Drug dependence
It is a physical or psychological condition resulting from repeated administration of mood-altering drugs.
It is a state characterized by a compulsion to take the drug on a continuous or periodic basis in order to experience its euphoriogenic effects.
If a mood-altering drug is unavailable, then the individual develops certain withdrawal symptoms.
Physical dependence + Psychological dependence
Drug addiction
Drug habituation
Drug abuse
Habit-forming drug
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

molecules of the haemoglobin; this is an
part of their anatomy.
• The presence of iron enables RBC to carry
oxygen, which is their function.
• All cells in the body must receive oxygen
in order to function properly, so the
physiology of RBC is essential to the
physiology of the body as a whole.

9. Pathology
Pathology is the study of the
abnormalities (diseases) of the
body and how they affect body
functions, often causing illness.

11. LEVELS OF STRUCTURAL COMPLEXITY
Within the body there are different
levels of structural organisation and
complexity.
13. Chemical level
•The chemicals that make up
the body may be divided into
two major categories:
ORGANIC AND INORGANIC.
14. Organic chemicals are often very complex and always contain
the elements carbon (C) and hydrogen (H).
e.g. carbohydrates, fats, proteins, and nucleic acids.
Inorganic chemicals are usually simple molecules made of one
or two elements other than carbon (with a few exceptions).
e.g. water, oxygen (O), carbon dioxide (CO2); and minerals
such as iron (Fe), sodium (Na), nitrogen (N), phosphorus (P),
calcium (Ca), and sulphur (S), are essential for maintaining life.
15. Cellular level
Molecules combine to form cells, the basic
structural and functional units of an organism.
The cells are smallest structural and functional
units of living body.
There are many different types of human cells,
though they all have certain similarities.
Each type of cell is made of chemicals and carries
out specific chemical reactions.

18. Tissue level
Tissues are groups of cells and the
materials surrounding them that work
together to perform a particular function.
There are just four basic types of tissue in
your body: epithelial tissue, connective
tissue, muscular tissue, and nervous tissue.
19.
20. Organ level
Organs are structures that are composed of two or more different
types of tissues; they have specific functions and usually have
recognizable shapes.
e.g. the kidneys, bones, the liver, lungs, and stomach. The
stomach is lined with epithelial tissue that secretes gastric juice
for digestion. Smooth muscle tissue in the wall of the stomach
contracts to mix food with gastric juice and push it to the small
intestine. Nerve tissue carries impulses that increase or decrease
the contractions of the stomach.

22. Organ systems level
Integumentary system
Skeletal system
Muscular system
Nervous system
Endocrine system
Cardiovascular system
Lymphatic system
Respiratory system
Digestive system
Reproductive system
23. a) Integumentary system
Organs: skin, epidermis, dermis and subcutaneous tissue
Functioning: It is a barrier to pathogens and chemicals. It prevents excessive
water loss. Skin also regulates body temperature.
b) Skeletal system
Organs: bones, ligaments, cartilages
Functioning: Supports the body. It protects internal organs and red bone
marrow. It provides a framework to be moved by striated muscles.
24.
25. a) Muscular system
Organs: skeletal muscles, tendons
Functioning: Moves the skeleton and also produces heat.
b) Nervous system
Organs: brain, spinal cords, cranial nerves and spinal nerves.
Functioning: Interprets sensory information and regulates body functions such
as movement by means of nerve impulses.
26.
27. a) Endocrine system
Organs: thyroid gland, pituitary gland, pancreas, adrenal gland
Functioning: Regulates body functions such as growth and reproduction by
means of hormones. Endocrine system also regulates metabolism of protein,
lipids and carbohydrates by means of hormones.
b) Cardiovascular system
Organs: heart, blood, arteries, arterioles, aorta, capillaries, veins
Functioning: Transports oxygen and nutrients to tissues and removes waste
products.
28.
29. a) Lymphatic system
Organs: spleen, lymph nodes, lymphatic vessels, tonsils & thymus gland
Functioning: Returns tissue fluid to the blood. It also destroys pathogens that
enter the body and provides immunity.
b) Respiratory system
Organs: lungs, trachea, pharynx, larynx, bronchi, diaphragm and intercostal
muscles
Functioning: The overall exchange of the gases oxygen and carbon dioxide
between the atmospheric air, the blood and the cells.
30.
31. a) Digestive system
Organs: mouth cavity, oesophagus, stomach, small intestine, colon, liver, gall
bladder and pancreas
Functioning: Break down of complex food to simple chemicals that can be
absorbed to blood and used by the body.
b) Urinary system
Organs: kidneys, ureter, urinary bladder, urethra
Functioning: Removes waste products from the blood. It regulates volume and
pH of blood and tissue fluid.
32.
33. a) Reproductive system
Organs: Female: ovaries, uterus, uterine tube & vagina
Male: testes, penis, urethra, prostate gland & seminal vesicles
Functioning: In women, provides a site (uterus) for the developing embryo and
fetus. In men, produces eggs or sperm.
34. Organismal level
• All the parts of the human body functioning together
constitute the total organism.
35. Homeostasis
Homeostasis is the maintenance of the internal environment
of the body.
Homeostasis is essential to survival; hence, many of the
body’s systems are concerned with maintaining this internal
environment.
Homeostasis is the condition of equilibrium (balance) in the
body’s internal environment due to the constant interaction
of the body’s many regulatory processes.
36. Homeostasis is a dynamic condition. In response to changing
conditions, the body’s equilibrium can shift among points in a
narrow range that is compatible with maintaining life.
A person who is in good health may be said to be in a state of
homeostasis. Homeostasis reflects the ability of the body to
maintain a relatively stable metabolism and to function
normally in spite of many constant changes.
Some examples of homeostasis are blood sugar levels, body
temperature, heart rate, and the fluid environment of cells.
When homeostasis is maintained, the body is healthy.
